Application June 17, 1935, Serial Na. 27, 121,

- 1 Claim. (Cl. 147-1) This invention relates to Woodworking mache inery and more particularly to a; butter tub reconditioning machine. V

The primary object of this invention resides in the provision of a machine adapted to hold butter tubs in position for planing or smoothing their outer peripheries.

Another object of this invention resides in the provision of a machine adapted to hold butter tubs or the like in rotary position for application of smoothing devices against their outer peripheries by workmen stationed at opposite ends of the machine.

A further object of this invention resides in the provision of a machine adapted to rotatably hold butter tubs at its opposite ends for application of smoothing devices in the hands of workmen stationed in convenient reach of individual controlling means for the tub upon which each is operating.

A still further object of this invention resides in the provision of a machine adapted to frictionally retain butter tubs at the outer ends of rotary counter-shafts driven from a main power shaft and controlled by means in convenient reach of workmen stationed at the opposite ends of the machine.

In addition to the aforesaid objects this invention resides in the provision of a machine comprising opposed counter-shafts provided with chucks fixed on their outer ends and connected to a, main power shaft by suitable driving means permitting each counter-shaft to be stopped and started at the will of workmen operating on the outer peripheries of the tubs.

Aside from the foregoing objects, this invention resides in the provision of a butter tub reconditioning machine, which among other elements, consists of end standards and an intermediate standard suspended therebetween by truss-rods connecting the end standards, said standards having aligned bearing boxes mounted thereon.

With these and other objects in view this invention resides in certain novel features of construction to be hereinafter set forth in the specification, illustrated in the accompanying drawings and pointed out in the appended claim and, while the disclosure depicts my present conception of this invention, the right is reserved to resort to such variations in construction as come within the scope of the claim.

In the accompanying drawings forming a part of this application:

Fig. l is a side View of a butter tub reconditioning machine as constructed in accordance with this invention. V

,Fig. 2 is anend view thereof.

Fig. 3;is a vertical sectional View on line 3-3 of Fig. 1.

Fig. 4 is a detail horizontal sectional view on line 4-4 of Fig. 2.

Fig. 5 is a detail perspective View of a portion of the belt shifting fork.

In the present embodiment of this invention the numeral 5 designates, in general, a machine adapted to rotatably support butter tubs at its opposite ends for the application of planing or smoothing devices held or controlled by worksists of substantially inverted V-shaped stand ards 6 suitably secured to sills l and having their legs 8 connected by cross-beams 9 adapted to support suitable bearing boxes ID at their medial points, said bearing boxes l0 being disposed in alignment to support a main shaft l l.

Suspended between the standards 6 as by trussrods l2 and braces I3 is an intermediate standard i l of substantially inverted V-shape configuration somewhat similar to the standards 6.

Suitably secured in alignment on the upper ends ofthe standards 6 and I4 is any approved type of bearing boxes l5 in which is journaled opposed counter-shafts l6 and I1, each having a pulley I8 splined thereon adjacent each of which is a loose pulley I9.

Secured to the outer ends of the aforesaid counter-shafts l6 and I! are chucks of substantially frusto-conical configuration for the reception of butter tubs or the like. These chucks are preferably covered with a rubberized or other suitable frictional material 2| so the tubs when pushed thereon will rotate with the countershafts and be easily removed upon completion of smoothing the outer peripheries thereof.

Splined or otherwise secured to the main shaft H are Wide pulleys 22 which are connected to the leversi'2l 'whichlare disposed at one side of the standards 6 adjacent the chucks 20V.

Connecting the standards 6 on that side thereof upon which the levers 21 are mounted is a beam '28: having secured thereto adjacent its media1 point spaced guide brackets 29 for loosely supporting the free ends of belt shifting rods 30'suitably "connected to the hand-levers 21 as shown 7 r in Fig; 6. The belt shifting rods 30 are provided 7 with forks 3| as shown in Fig. 5 and, through the Vinstrumentality of the same, power is transmitted from the constantly rotating main shaft 1 I r to V 7 either or both of the counter-shafts i6 and Ilgby.

the belts when thehand-levers are pushed or rockedinwardly.

With this invention constructed asaforesaid it is manifest that a machine is provided whereby butter tubs can be readily reconditioned in an expedient manner and through the' particular; disposition of I the controlling means, the workin e'nat opposite ends of the machine can conduct their work individually. Further; through the instrumentality of the particularly constructed. 7 frame vibration is reduced to the Having thus fully described my invention what 7 I claim and desire to protect by Letters Patent A butterfltub reconditioning machine jot the shaped standard of lesser length than the first mentioned standardsdisposed :abovethe planez upon which the base of the-first mentioned standards rest, means connecting the intermediate standard to the legs of the first mentioned stand ards, opposed counter shafts journaled on the upper extremities of-the standards with their 5 innererids terminating at the intermediate standard, yielding chucks secured to the outer ends of r the counter shafts, power transmitting means connecting the main power shaft with the counter V shafts, and means associated with the power 20 transmitting -m'eans for -dispo'sing "the; power transmitting means in idling .pos'itionrelati've V the counter shafts.
